I use Air Droid and ES file explorer on 3 tablets and 2 phones. Both are free, easy and quick.
Air Droid will allow you to download your stuff from Android to a PC very quickly but it is manual, no automation or sync (for free version anyway).
ES allows you to use your network to copy from phone to a PC using FTP, SMB/CIFS, or cloud, again, manual and no automation.
